SHAFT-COUPLING.

Specification of Letters Patent.

Patented March 24, 1908.

Applicatiim filed May 28, 1907. semi No. 376,135.

To all whom it may concern:

it known that we, ARTHUR H. BOMMER and WiLLiAM J. ROBERT, citizens of the United States, and residents of St. 'Louis, liiissouri, have invented certain new and useful ln'iprovements in Shaft Cou1')lingsj of which the following is aspecificetion.

This invention relates to improvements in shal'tv ouplings, and consists in the novel arrangement. cor struction, and combination of parts as will be fully hereinafter described and claimed.

The object of our invention is to construct a coupling rigidly retained in position upon the side of the vehicle, and a means whereby the shnft member is detachobly connected to tllii held in locked position to the axle.

A. further object of our invention is to construrt a slmft-crmpling composed of two members detachably secured together and so arranged as to lock the same when placed in operative position to prevent rattling and at the same time from becoming detached while in its operative position. A

in the drawings: Figure 1 is a vertical central soctionz'li view of our invention shown in operntive position. Fig. 2 is a side elevation of one of the men'ibers showing it attached to the axle of the vehicle. Fig. 3 is a side clevation of the shaftmember of the coupling.-

Fig. {i is e cross-sectional View taken on the line 4 4 oi' ifigf 1.

in the constructmn of our invention we provide a member 5 to which is suitably attached a sprii'ig (i. and to the opposite end of the member is hingedly attached a jew 'Z. The member 5 and the jaw 7 are each providod with a semicircular:recess 8 which forms a complete circular opening when the member 5 and jaw 7 are in closed position as shown in Fig. 1. The member 5 is attached tr, axle 9 of the vehicle by the usual clips it The spring 6 is provided with a bent portion 1 i and n hook 12 which form recesses in which are supported links 13 and 14, the link 13 passing upwardly and ground the member 5 over the jaw 7 and resting in a. semicircular groove 15 formed in the upper surface of the jaw and to the roar of the semicircular opening.

in the opening formed by the member 5 and jaw 7 is placed the pin member 16, its ends securely fastened to the bifurcated end 17 of the sheft member 18 and upon the projecting ends of the pin 16 are located the she ends 19 of the link 14 and are prevented from becoming detached from the ends of the pin by means of thewashcrs. or the like 20. The shaft member 18 terminates into a flattened portion 21 by which the coupling is secured to the shaft 22 which is done by riveting or bolting as found most desirable.

By means f the link 14 being carried by means of a tension upon the link 14 will hold the pin 16 in the semi-circular recess of the member 5. The jaw 7 is held in locked osition upon the pin by means of the lin 1b and held in this position by the tension of the spring 6. The spring in this connection prevents the members from becoming disconnected and at the some time acts as an anti-rattler, and yet permits sufficient movement between the shaft and. axle to accom modate the irregularities on the surface over which the vehicle is being propelled.

By a device of this construction separate washers are dispensed with, end there is no possible way in which the shaft may become disconnected from the vehicle by accident while the vehicle is being propelled by the animal. r

Having fully described our invention, what we claim is:

1; A shaft-coupling comprising on axle member, a jaw pivotally connected to the axle member a. spring carried by the axle member, s shaft member dctzichsbly hold in position upon the axle member, a link C81!- ried by the shaft member and contacting with the spring to retain the shaft member in contact with the axle member and a. link surrounding the jaw,- axle member and spring, substal'itially as specified.

2. A shaft coupling comprising an axle member provided wit-he scmecircular recess,

a jaw provided with a corresponding some circular recess and hinged to the front end of the axle member, a shaft member, a pin carried by the shaft member to rest in the semicircular recesses formed by the axle member and jaw, a spring carried by the axle member and extending horizontally beneath the some, a. link carried by the pin and supported mcm'b'er, substantially as specified.

end of the spring, 'a i names to this specification, in presence of two subscribing witnesses.
